Venizelism (Greek: Βενιζελισμός) was one of the major political movements in Greece beginning from the 1910s. The movement first formed under Eleftherios Venizelos in the 1910s and saw a resurgence of support in the 1960s when Georgios Papandreou united a coalition of old Venizelists and nationalist politicians.
The movement was characterized by the beliefs of Eleftherios Venizelos and the ideas of Greek irredentism supporting the Megali Idea. It had a Francophile stance as the ideas of the French Revolution and the idea of one state which should have all the lands predominantly inhabited by a single ethnicity. In WWI, the Venizelists wished to join the Entente, mainly due to the entrance of the Ottoman Empire and Bulgaria, which was one of the highest chances to gain all lands Greeks claim and thus fulfilling the Megali idea. Despite popular misconceptions, Venizelism is a movement that sides with monarchy, and it calls for a ruling class in which the urban class can rise to the ranks by merit. Additionally, the king should originate from the same country that he is ruling, thus not having loyalties to foreign interests. Venizelism called for early and more moderate capitalistic economic policies such as open markets, but the government should approve those markets. The movement had its strongest support in Crete, Thrace, Epirus, the North Aegean islands, and Macedonia.
